According to certain embodiments of the present disclosure, the biometric data generator 322 obtains a biometric image such as a fingerprint image, iris image, and face image. For example, the biometric image is obtained by an optical method using reflection of light or non-optical method using a pressure, heat, and ultrasonic waves. The biometric data generator 322 extracts inherent characteristic information based on a biometric image of a person. For example, the characteristic information for identifying a fingerprint can be minutiae, such as a ridge end, bifurcation point, core point, and delta point of a line. The biometric data generator 322 can be calculated in a format or frame predetermined for identifying a matching degree with stored biometric registration data. For example, the information of the predetermined format can be provided in a template form.

The biometric data generator 322 stores the generated biometric data in a memory as registration information if registration of the biometric information is requested. In certain embodiments, the request for registration of biometric information is received through a security signal transmitted from the general area.

The data matcher 324 identify whether biometric authentication data input for biometric identification matches stored biometric registration data if the biometric identification is requested. In certain embodiments, the request for biometric identification is received through a security signal transmitted from the general area.

According to various embodiments of the present disclosure, the data matcher 324 compares specific information calculated from biometric authentication data input for biometric identification with at least one of registered data and calculate a matching value. The matching value is a value indicating matching information between the biometric authentication data and biometric registration data. For example, the matching value is calculated as the number of characteristic points identified to be corresponding or identical to each other from the characteristic points included in biometric data while matching data. In certain embodiments, the matching value is calculated according to statistical data or probability functions by considering the similarities of distances, directions, or disposition forms between characteristic points included in the biometric data. The data matcher 324 identifies success in biometric authentication based on a matching value of specific information. For example, the data matcher 324 decides that the biometric authentication succeeds when the matching value is greater than a predetermined value and decides that the biometric authentication failed when the matching value is less than the predetermined value. The data matcher 324 controls the biometric authentication, so that result information relates to the success in authentication (for example, a true or false signal) for a biometric identification function module in the general area. The security processor 326 encrypts and decrypts the biometric data. The security processor 326 generates a unique key based on specific identification information of a device. For example, the unique key is an accessible value in a security mode. According to certain embodiments of the present disclosure, the security processor 326 encrypts the biometric data and stores the encrypted biometric data in the secure area 137 of the memory 350 by using a unique key while registering biometric information. The security processor 326 obtains the encrypted biometric data from the secure area 137 and decodes the obtained biometric data by using the unique key while authenticating biometric identification. The security processor 326 transmits the decoded biometric data to the data matcher 324. In certain embodiments, a function for generating a unique key is used while operating in a virtual security core system, but is restricted to access while operating in a general compensation core system. According to certain embodiments of the present disclosure, the security processor 326 encrypts the biometric data by using a unique key and transmits the encrypted biometric data to a biometric identification function control module (for example, virtual general core 111 of FIG. 1B) in the general area. The security processor 326 receives the encrypted biometric data from the biometric identification function control module in the general area when a live object is identified and decodes the encrypted biometric data by using a unique key generated in a security mode. The security processor 326 transmits the decoded biometric data to the data matcher 324. According to certain embodiments of the present disclosure, the security processor 326 generates pseudo data by transforming biometric data by using a transform function. The transform function includes a one-way function, data arrangement function, or function utilizing a value obtainable from a security mode or separate security hardware. The transform function stores the biometric data as metadata. The security processor 326 transmits the generated pseudo data to the data matcher 324 and the data generator 322. For example, the dater generator 322 stores the pseudo data as registration information. The data matcher 322 decides success in biometric authentication by comparing the registered pseudo data and newly generated pseudo data.

The security processor 326 differently utilizes the transform function for generating pseudo data. For example, when biometric identification information is unintentionally exposed to the outside, the security processor 326 modifies the transform function and generates new pseudo data by using the modified transform function. The metadata of biometric data is also renewed if the biometric data is exposed to the outside, and thereby the security processor 326 revises or discards the existing biometric data. According to various embodiments of the present disclosure, in an electronic device 300 operating with a general area 135 and secure area 135 through one processor 320, the processor 320 is included so that an input event of biometric information is detected from a biometric sensor module for recognizing a body in a general area, the input event of biometric information in the general area is transmitted to a secure area 137, sensing data is obtained from a biometric sensor module responding to the input event of biometric information in the secure area 137, and result information of registering biometric information and biometric identification is transmitted to the general area by processing the sensing data obtained from the secure area 137. In the secure area 137, the processor 320 calculates specific information from the sensing data, generates biometric data based on the specific information, encrypts the biometric data by using a unique key generated based on inherent identification information, and registers the encrypted biometric data as biometric information. The processor 320 transmits the encrypted biometric data to the general area and stores the biometric data encrypted in the general area.

The processor 320 obtains encrypted registration data from a memory allocated by the secure area 137 or general area, decodes the encrypted registration data by using a unique key generated based on inherent identification information, performs biometric authentication by comparing the decoded registration data and generated biometric data, decides that the biometric authentication succeeded if a matching value of data is greater than a predetermined critical value according to the result of comparison, and decides that the biometric authentication failed if the matching value of data is less than the predetermined critical value. The processor 320 transmits a true or false signal corresponding to the result of registration or identification. The processor 320 generates pseudo data by transforming the biometric data through a transform function, encrypt the pseudo data, and store the encrypted pseudo data as biometric registration information. When authenticating biometric identification, the processor 320 performs biometric identification authentication based on the pseudo data. The processor 320 s modifies the transform function if the biometric information is exposed to the outside. The transform function uses a value provided by a security mode or separate security hardware. The memory 350 corresponds to the memory 230 of FIG. 2. The memory 350 includes authentication information DB 351, authentication information 352, and application 353. The application 353 corresponds to the application 134 of FIG. 1A. The authentication information DB 351 includes information combined with semi-permanent or permanent representative authentication information related to an account and temporary authentication information for an additional authenticating procedure. The account applied to various embodiments of the present disclosure is defined as follows. “Account” means a user ID and password assigned when a user become a member of internet service provider and PC communication service. “Representative authentication information” means an account including an ID and password. The authentication information 352 includes representative authentication information and temporary authentication information. The representative authentication includes a fingerprint and iris pattern as well as an account. The temporary authentication information includes facial identification, using a camera or a facial recognizing sensor, and peripheral device information identified through the wireless communication unit 310. The account is input when authentication is requested in an application 353 requiring personal information. Connection information, such as representative authentication information and temporary authentication information, is stored in the authentication information DB 351, and detailed description will be made referring to Table 1.

TABLE 1 Data list of authentication information DB Representative Temporary Account Account Application authentication authentication No. ID PWD information information information 1 A1 P1 Google Fingerprint 1 Face 1 2 A2 P2 Google Fingerprint 2 Watch 1 3 A3 P3 Cloud Iris Pattern 1 Side touch application sensor

Referring to Table 1, the processor 320 stores an account identification (ID) or information characterized by the account ID, account password (PWD) or information characterized by the account PWD, information of application 353, representative authentication information or information characterized by the representative authentication information, and temporary authentication information or information characterized by the temporary authentication information in the authentication information DB 351. The representative authentication information includes an account ID and account PWD. Table 1 illustrates three examples of not including the account ID and PWD according to various embodiments of the present disclosure. Referring to the first example of Table 1, the processor 320 stores representative authentication information and temporary authentication information of application 353 (such as GOOGLE® account information A1 and P1) as illustrated in Table 1. The representative authentication information of the GOOGLE® account is a first fingerprint and the temporary authentication information is a first face. User authentication is made with the first fingerprint through a fingerprint recognizing sensor of the sensor unit 330. The processor 320 recognizes a face by controlling a face recognizing sensor of the camera 340 or sensor unit 330 and stores the face as temporary authentication information. Subsequently, the processor 320 maintains an authentication state when the temporary authentication information identified by controlling the face recognizing sensor of the camera 340 or sensor unit 330 is identical to the first face stored in the authentication information DB 351. The authentication state is released when the temporary authentication information is not identical to the first face stored in the authentication information DB 351.

Referring to the second example of Table 1, the processor 320 stores representative authentication information and temporary authentication information of application 353 (such as GOOGLE® account information A2 and P2) by mapping as shown in Table 1. The representative authentication information of GOOGLE® account is a second fingerprint and the temporary authentication information is a first watch. The processor 320 performs user authentication by using the second fingerprint through the fingerprint recognizing sensor of the sensor unit 330 and stores the first watch as temporary authentication information by controlling the wireless communication unit 310. The processor 320 identifies whether the first watch is located within a predetermined distance by using a near-field communication of the wireless communication unit 310, such as a Bluetooth communication. When the first watch is identified to be located within the predetermined distance, the processor 320 maintains the authentication state. When the first watch is identified not to be located within the predetermined distance, the processor 320 releases the authentication state. Further, the processor 320 identifies whether the first watch is worn by a user by receiving information from a contact sensor integrated into the sensor unit 330 or from a peripheral device through the wireless communication unit. For example, a heart rate measuring sensor is integrated as the contact sensor. When the first watch is identified as not worn by the user, the processor 320 releases the user authentication. The processor 320 identifies the temporary authentication information with at least one of the distance and wearing state.

Referring to the third example of Table 1, the processor 320 stores representative authentication information and temporary authentication information of application 353 (such as account information A3 and P3 of a cloud application) by mapping as illustrated in Table 1. The representative authentication information of cloud application is a first iris pattern and the temporary authentication information is a side touch sensor. The processor 320 recognizes the first iris pattern through the sensor unit 330 and recognizes and stores the side touch sensor as temporary authentication information through the sensor unit 330. The processor 320 releases the user authentication when the side touch sensor is deactivated.

The apparatus for controlling an authentication state of an electronic device according to various embodiments of the present disclosure includes a display unit configured to display a screen requesting user authentication for a first application; a sensor unit, camera, and wireless communication unit configured to recognize temporary authentication information and representative authentication information; a memory configured to store information including at least one of the temporary authentication information and the first application, and an authentication information DB for storing information required to connect the representative authentication information; and a controller configured to authenticate user login with representative authentication information in a first application requiring user authentication, to identify temporary authentication information when authenticating the user in the first application, to store the identified temporary authentication information and the representative authentication information, to decide whether temporary authentication information is identical to the stored temporary authentication information by identifying the temporary authentication information while using the first application, and to maintain an authentication state if the temporary authentication is identical to the stored temporary authentication information.

FIG. 4 illustrates an exemplary process of storing representative authentication information and temporary authentication information in a memory for an account according to various embodiments of the present disclosure.

Hereinafter, the representative authentication information includes account information described differently from Table 1. A method of requesting for representative authentication information is described with an application, but the method is not limited to the application and can be performed through a browser or website application.

In step 401, the processor 320 controls the display unit 360 to display an input screen for representative authentication information of the application 353 at operation 401. In step 402, the processor 320 identifies representative authentication information of the application 353 input by a user. In step 403, the processor 320 decides whether to store the representative authentication information according to the user's selection. In step 404, when storing is selected by the user, the processor 320 stores the representative authentication information in the authentication information DB 351 by combining with application information.

FIGS. 5A and 5B illustrate exemplary processes of controlling an authentication state according to certain embodiments of the present disclosure.

In step 501, the processor 320 controls the display unit 360 to display an input screen for representative authentication information of the application 353. In step 502, the processor 320 identifies first representative authentication information and first temporary authentication information input by a user. In step 503, while performing the authentication, the processor 320 stores information which connects the application 353, first representative authentication information, and first temporary authentication information in the authentication information DB 351. In step 504, while executing the application 353, the processor 320 identifies the temporary authentication information. In step 505, the processor 320 identifies whether the identified temporary authentication information is identical to temporary authentication information stored in the authentication information DB 351 by connecting to the first representative authentication information. In step 506, when the identified temporary authentication information is identical, the processor 320 maintains the authentication state.

In step 507, the processor 320 identifies whether execution of a second application is requested. When execution of a second application is not requested, the processor 320 returns to step 504 and identifies the temporary authentication information again. The processor 320 identifies the temporary authentication information when an execution time of at least one of an application or browser elapsed a predetermined time or an additional authentication is required.

In step 508, when a request for executing the second application is identified at step 507, the processor 320 controls the display unit 360 to display an input screen for a second representative authentication information of the second application at operation 508. In step 509, the processor 320 identifies whether second representative authentication information and second temporary authentication information for logging into the second application are input by a user. In step 510, when authenticating user login, the processor 320 stores the information which connects the second application, the second representative authentication information, and the second temporary authentication information in the authentication information DB 351. In step 511, the processor 320 identifies whether the second temporary authentication information is identical to the first temporary authentication information. In step 512, when the identified temporary authentication information or the second temporary authentication is not identical, the processor 320 releases a login state. In step 513, when the second temporary authentication is identical, the processor 320 maintains the login state.

FIG. 6 illustrates an exemplary process of controlling an authentication state according to certain embodiments of the present disclosure.

Referring to FIG. 6, the processor 320 controls the display unit 360 to display an input screen for a first application 601 a. The processor 320 then identifies whether first representative authentication information 600 is input by a user. While authenticating the user login, the processor 320 stores information which connects the first application 601 a, a first representative authentication information 600, and a first temporary authentication information in the authentication information DB 351. After authenticating, the user logs into the first application 601 a. Namely, the processor 320 controls the display unit 360 to display information of the first application for the user. At the same time of logging into the first application or after a predetermined time interval, the processor 320 identifies a temporary authentication information 610. The processor 320 identifies whether the identified temporary authentication information is identical to first temporary authentication information stored in the authentication information DB 351 by connecting to first representative authentication information. The processor 320 makes a request for identifying the temporary authentication information after terminating the first application 601 a, when execution of second application 602 is requested or after the execution time of the first application elapsed a predetermined time. As shown in FIG. 6, the processor 320 makes a request for temporary authentication information when the execution of the second application 602 is requested. When the representative authentication information input for the second application 602 is first representative authentication information, the processor 320 identifies whether temporary authentication information is identical to first temporary authentication information stored in the authentication information DB 351 by connecting to the first authentication information.

When the temporary authentication information 610 a is identified to be identical to the first representative authentication information, the processor 320 controls the display unit 360 to display information of the second application 602. When an input for the first representative authentication information is identified corresponding to a request for executing the first application 610 a, the processor 320 performs a procedure of temporary authentication. When the identified temporary authentication information 610 a is identified to be identical to the first temporary authentication information, the processor 320 controls the display unit 360 to display information of the first application 601 a. When the processor 320 makes a request for identifying temporary authentication information after the execution time of the first application 601 a elapsed a predetermined time. When the first temporary authentication information 610 is not identical to the temporary authentication information 610 b, the processor 320 releases a login state of the first application 601 a. The processor 320 then cannot log into the first application 601 b until temporary authentication information 610 b becomes identical to the first temporary authentication information 610.

FIG. 7 illustrates an exemplary process for registering biometric authentication information of an electronic device according to certain embodiments of the present disclosure.

In step 710, the processor 320 detects an input event of biometric information based on an interrupt signal transmitted from the biometric sensor module 180 in the general area 135 for registering biometric information, for example, in a registration mode. When a function for registering biometric information is generated in the general area 135, the processor 320 activates the biometric sensor module 180 and detects an object through the biometric sensor module 180. For example, the processor 320 identifies a user's finger touch by using a fingerprint sensor. The processor 320 identifies a user's eye by using an iris sensor. The processor 320 identifies a user's hand approaching to a sensor by using a vein sensor. The processor 320 identifies a user's voice by using a voice sensor. The processor 320 identifies a user's face by using a face recognizing sensor.

In step 720 when an input event of biometric information is detected, the processor 320 transmits an event detection signal to the secure area 137 in order to call a virtual security core system. In certain embodiments, the event detection signal is a security interrupt signal.

In step 730, the processor 320 obtains sensing data from the biometric sensor module 180 in the secure area 137. The sensing data is raw data of the biometric information. For example, the sensing data includes at least one of a user's fingerprint, lines of a palm, retina pattern, iris pattern, blood vessel pattern, ear shape, face shape, user's voice, and handwriting sample.

In step 740, the processor 320 calculates inherent characteristic information of identified object in the secure area 137 based on the sensing data. For example, the processor 320 obtains a sensing image from the sensing data and extracts specific information from the sensing image.

In step 750, the processor 320 generates biometric data in the secure area 137 by transforming the specific information to a template form.

In step 760, the processor 320 encrypts the biometric data in the secure area 137. For example, the processor 320 generates a unique key in the secure area 137 based on inherent identification information of a device. The unique key is a value accessible in a security mode. For example, the processor 320 stores function information for generating a unique key in a memory allocated by the secure area 137 and generates a unique key through the function information in the security mode. Step 760 can be omitted; however the present disclosure is not limited to this.

In step 765, the processor 320 transmits the biometric data encrypted in the secure area 137 to the general area 135. For example, the processor 320 stores the encrypted biometric data in a memory allocated by the general area 135, for example, an REE file system.

In step 770, the processor 320 stores and registers biometric data or encrypted biometric data in the secure area 137 as registration data for biometric identification. According to certain embodiments of the present disclosure, processor 320 stores and registers the biometric data in the secure area 137 accessible in a security mode. According to certain embodiments of the present disclosure, the processor 320 stores a unique key used for encryption or function information for generating a unique key in the secure area 137 accessible in a security mode, and transmit encrypted biometric data to the general area 135. The processor 320 stores and registers the encrypted biometric data, which is transmitted from the secure area 137, in the general area 135 having no access limitation.

In step 780, the processor 320 transmits the result of biometric registration from the secure area 137 to the general area 135. In step 790, the processor 320 provides a user with registration information of biometric information, which is registered in the general area 135 by a virtual general core, through a user interface or a component of the electronic device 300.

When the registration of biometric information fails due to a low quality of raw data, the processor 320 performs the procedure of registration again. The processor 320 provides at least one of a feedback for the failure of registration, for example, by using a visual or acoustic effect, and new sensing data through a user interface in the general area 135.

FIG. 8 illustrates an exemplary process for authenticating biometric information of an electronic device according to certain embodiments of the present disclosure.

In step 810, for biometric authentication (for example, in an authentication mode), the processor 320 detects an input event for biometric information based on an interrupt signal transmitted from the general area 135 to the biometric sensor module. When a function for biometric authentication is requested in the general area 135, the processor 320 activates the biometric sensor module 180 and detects an object through the biometric sensor module 180.

In step 820, when an input event for biometric information is detected in the general area 135, the processor 320 transmits an event detection signal to the secure area 137. In certain embodiments, the event detection signal is a security interrupt signal.

In step 830, the processor 320 obtains sensing data from the biometric sensor module 180 in the secure area 137. In step 840, the processor 320 calculates inherent characteristic information based on the sensing data obtained in the secure area 137 and generates biometric authentication information. In certain embodiments, the biometric authentication data includes a predetermined format such as a template form.

In step 850, the processor 320 receives encrypted biometric registration data in the secure area 137 from the general area 135 or obtains the encrypted biometric registration data from a memory allocated in the secure area 137. In step 860, the processor 320 decodes biometric registration data (for example, encrypted biometric data) stored in the secure area 137. For example, when the encrypted biometric data is obtained from the secure area 137, the processor 320 decodes the encrypted biometric data using a unique key. The processor 320 obtains function information for generating a unique key from a memory allocated by the secure area 137 having an access limitation and generates the unique key by using the obtained function information.

In step 870, the processor 320 calculates a matching value by comparing characteristic information of biometric authentication data and biometric registration data in the security area 137. In step 880, the processor 320 decides the success in the biometric authentication based on the matching value of specific information in the secure area 137. For example, when the matching value exceeds a predetermined critical value, the processor 320 decides that the biometric authentication succeeded. When the matching value is less than the predetermined critical value, the processor 320 decides that the biometric authentication failed.

In step 885, the processor 320 transmits the result of biometric authentication from the secure area 137 to the general area 135. In step 890, in the general area 135, the processor 320 provides a user with the result of biometric authentication through a user interface or a component of the electronic device 300.

When the identification of biometric information failed due to a low quality of raw data, the processor 320 performs the procedure of identification again and provides the user with at least one of a feedback for the failure of identification (for example, by using a visual, acoustic, tactile, or olfactory effect) and obtainment of new sensing data through a user interface in the general area 135.
